Since its launch in 2020, the Wharfedale DIAMOND 12 Series has received widespread praise as a standard for performance and value in affordable hi-fi speakers. After over five years of consistent success, awards, and positive reviews from audio enthusiasts and critics alike, the DIAMOND 12 Series has established itself as one of the most enduring and best-selling speaker series.

Now, Wharfedale is excited to introduce the updated DIAMOND 12i Series. This new series features luxurious, modern finishes and subtle acoustic improvements that build on the strong foundation of the original design.

Known for quality, affordability, and exceptional build quality, the Wharfedale Diamond series has always prioritised fit and finish. The new luxurious finishes enhance the loudspeaker’s premium look and feel, matching its impressive sound performance.

Along with the aesthetic upgrade, Wharfedale’s engineering team revisited the speaker’s internals, paying special attention to bass port tuning and airflow control. Small but significant changes to the port design and internal damping have improved bass clarity and low-frequency control—especially in real-world environments. Listeners will notice the difference.

The DIAMOND 12i mid/bass driver cones remain unchanged and are made from Klarity™, a special blend of polypropylene and mica that provides excellent stiffness and low distortion. This results in a cone that is lightweight, well-damped, and very responsive, delivering natural, expressive dynamics and precise transient response.

A low-damping surround enhances the cone’s efficiency and dynamic range, while ribbed shaping and profile simulation ensure a smooth, linear frequency response without added distortion.

Each mid/bass driver features a precise magnet system with an aluminium compensation ring to reduce the effects of inductance changes as the voice coil moves. This advanced motor system minimises intermodulation and distortion, producing cleaner, more accurate sound.

The voice coil is wrapped around a high-power epoxy/glass fibre bobbin, which performs significantly better than standard materials at this price point, offering greater power handling, thermal stability, and structural strength.
